Newline after receiving "AA" on Windows Application Form

Question

Hello I am designing a Protocol Data analyzer in c# by using Windows application Form. I am receiving data at speed of 5.25 Mbps from COM Port & i want to show this data over Windows Application. So now i am able to get data over window. However i want to split string to newline & show the time as soon as i get AA (AA is my Preamble in protocol Header). My Protocol data stream is as mentione below: AA 01 00 13 59 A1 02 61 6A A1 02 61 09 00 01 81 00 01 9B D3 32 72 23 AA I have attached my source file. So how i can do this? Any suggstions?

ok you got the solution but before you were using StringBuilder now why did use buffer?

sumit Kale · Answer

Solved by using following Line: Log(LogMsgType.Incoming string.Format(Sniffer Logged in {0}
 DateTime.Now) + ByteArrayToHexString(buffer).Replace(AA
AA) + string.Format(
)); // Show the user incoming data in Hex format & after each 10 second update the data coming & post it on the newline

Using wordwrap= false; its firing error. About label also its firing error. Do i need to change my design?

you can use richtexbox itself but yo have to make word wrap=false sb = sb.Replace(AA 
AA); richTextBox1.WordWrap = false ; richTextBox1.Multiline = true; richTextBox1.Text = sb.ToString();

private string ByteArrayToHexString(byte[] data) { StringBuilder sb = new StringBuilder(data.Length * 3 ); foreach (byte b in data) sb.Append(Convert.ToString(b 16).PadLeft(2 '0').PadRight(3 ' ')); sb=sb.Replace(AA
AA); return sb.ToString().ToUpper(); } try this its working perfectly here

Rafnas T P · Answer

or try this sb= sb.Replace(AA 
AA);

sumit Kale · Answer

Basically its printing same result which was my doubt. I want to put string starting from AA to next line till it receive another AA. Ex: AA xx xx xx xx xx xx xx xx AA xx xx xx xx xx xx xx xx

Rafnas T P · Answer

ok try giving only sb.ToString().Replace(AA 
AA); private string ByteArrayToHexString(byte[] data) { StringBuilder sb = new StringBuilder(data.Length * 3 ); foreach (byte b in data) sb.Append(Convert.ToString(b 16).PadLeft(2 '0').PadRight(3 ' ')); //sb=sb.ToString().Split(AA); sb.ToString().Replace(AA
AA); //sb.Append(
 AA); //sb=sb.Append(string.Format(AA{0}AA Environment.NewLine)); return sb.ToString().ToUpper(); }

Hello Rafnas T P I tried to do by your method. However its showing me error: Cannot implicitly convert type string to system.Text.StringBuilder .

Rafnas T P · Answer

private string ByteArrayToHexString(byte[] data) { StringBuilder sb = new StringBuilder(data.Length * 3 ); foreach (byte b in data) sb.Append(Convert.ToString(b 16).PadLeft(2 '0').PadRight(3 ' ')); //sb=sb.ToString().Split(AA); sb=sb.ToString().Replace(AA
AA); //sb.Append(
 AA); //sb=sb.Append(string.Format(AA{0}AA Environment.NewLine)); return sb.ToString().ToUpper(); }

Rafnas T P · Answer

if you wanted to come next line then try as below sb =sb.ToString().Replace(AA
AA); if you wanted to split then try as below sb =sb.ToString().Split(AA);
